| Abstract: Mo-doped Ce/GE catalysts with different loading amounts were prepared by impregnation method, which were examined as catalysts in the selective catalytic reduction of NOx by NH3(NH3-SCR). Furthermore, the intrinsic mechanism of Mo-doped Ce/GE catalysts for enhancing SCR activity was preliminarily investigated. It was found that the addition of Mo can increase the ratio of nCe3+/(nCe3++nCe4+), the oxygen content on the surface and the acid sites of the catalyst, thus enhancing SCR activity. Compared with 5Ce/GE and 5Mo/GE, 5Ce-5Mo/GE catalyst showed more outstanding catalytic activity. In addition, the catalyst exhibited the best activity and almost 99% conversion of NOx at 250℃, when the loading amount is 5%. 5Ce-5Mo/GE catalyst exhibited good sulfur resistance performance. |
